The rule

The core rule is that nouns ending in -o are typically masculine, while those ending in -a are usually feminine. However, there are exceptions. The definite article 'el' is used for masculine nouns, and 'la' is used for feminine nouns. The indefinite articles are 'un' for masculine and 'una' for feminine.
